FOLDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 240,235, dated April19, 1881.

Application filed May 11, 1880.

To all whom it may concern Be it known that I, LUTHER O. OnowELL, acitizen of the United States, residing in the city of Brooklyn, countyof Kings, and State of New York, have invented certain new and usefulImprovements in Folding-lllachines, fully described and represented inthe following specification and the accompanying draw ings, forming apart of the same.

In said drawings, Figures 1 to 5 illustrate a machine embodying theinvention in one of its forms, of which Fig. 1 is a side elevation Fig.2, a plan; Fig. 3, an end elevation; Figs. at and 5, views of theturning-surfaces disposed so as to deliver the folded paper verticallyat opposite sides of the machine, and Fig. 6 a vertical section of thetumors on'the line a of Fig. 5.

1 Another machine embodying the invention is shown in Figs. 7 to 11, ofwhich Fig. 7 is a side elevation; Fig. 8, a plan view; Fig. 9, an endelevation; and Figs. 10 and 11 views of the turning-surfaces disposed soas to deliver the folded paper in the opposite direction from that shownin Fig. 9. Fig. 11 is a sectional elevation of the turning-surfaces onthe line 0 of Fig. 10. Figs. 12, 13, 14, and 15 illustrate one mode ofarranging these turning-surfaces with a printing-machine, so as to 0deliver the printed sheets therefrom and fold the same eitherlongitudinally or both longitudinally and transversely, Fig. 12 being anend elevation, Fig. 13 a side elevation with cutting-cylinders insection, Fig. 14 a rear 5 view, illustrating the lower main tapes only,and Fig. 15 a detail. Fig. 16 is a perspective view of a machineembodying two longitudinal-folders. v

The folding apparatus, constituting the prin- 0 cipal portion of thepresent improvement, while capable of folding a web or sheets of anymaterial longitudinally, is more especially designed to form a part ofthe delivery mech anism of that class of printing-machines which 4 5operate to perfecta web of paper by printing thesame upon its oppositefaces while it passes once through-the machine. The chief obstruction tosuch machines running at the very high speed of which their rotaryprinting mechanisms are capable formerly existed in the mechanismprovided for delivering the product.

(ModeL) This has been provided for by a rotary sheetcollecting mechanismand a rotary sheet-folding mechanism; and while the former is capable ofdelivering sheets in the flat form at the requisite speed, the latter isonly capable of attaining that speed when the first fold in the sheet isformedtransversely to the line of travel of the sheet. In all machineswhere the first fold madeis longitudinal, or in the direction of thetravel of the sheet, and is produced by a foldin g-blade, such sheet isarrested or checked in its onward movement in order that it may beproperly so folded, because that operation changes its movement to oneat 6 right angles to the direction of travel it has as it enters thefolding mechanism. This stopping or partially stopping the travel of thesheet greatly modifies the speed of manipulation and interferes with theaccuracy of fold- 7o ing, because the time thus necessarily consumed indelivering the sheet, from one set of active mechanisms to another, eachcarrying the paper in difi'erent directions, will cause the sheet beingfolded to be overtaken by the succeeding one, while both are required tobe in an exact correlation at the instant the folding operation isperformed. In order to accomplish this with accuracy there is imposed alimit of speed upon such a delivery mechanism which is greatly withinthat at which the printing-machine may be operated.

The present invention relates to the structare of a folding devicewhereby a length of material passed through it is folded on a lineparallel with the direction of its travel, which said folding device,though particularly designed to fold webs or long lengths of mate--rial,is capable, with some modification, of folding in like manner shortpieces of material in 0 the form of sheets.

This improvement consists, primarily, of a folder constituted bystationary turners arranged in such a manner that a web or sheet passingover them will be folded longitudi- 5 nally, or in the direction of itstravel, which operation laysone section of the web or sheet upon theother, thus doubling it, andat the same time reducing its dimensionswidthwise accordingto the relation the line of folding [CO bears to thecenter of the web or sheet.

The invention further comprchends certain modifications of the structureof parts and various combinations of the folder with feeding anddelivering mechanisms, all of which is too particularly hereinafter setforth to need further preliminary description.

A' machine embodying the folding mechanism in its simplest formwillfirst be described. Such a one is illustrated by Figs. 1 to 6. Itsfolding mechanism consists of three foldingbars or turners, 3, 5, and 7,stationary in the sense of not turning, all of which turners arearranged to meet at a common point at which the line of creasing orfolding is determined. The turners 3 and 5 spread at such angles to eachother as to afford a surface capable of supporting the web distendedwidthwise, (see Fig. 2,) the turner 3 preferably standing at an angle ofabout one hundred and thirty-five degrees with respect to the turner 5.The turner 7, whose upper face is preferably inclined at an angle ofabout ninety degrees to that ofthe turner 5, has its inner face locatednearly in the same vertical plane with that of the turner 3, so that thesections of the web or sheet folded toward each other and movingrespectively over the turners 3 and 7 are brought nearly together.

The turners 3, 5, and 7 may be straight or conical bars, or simple wiresor edges provided by any rigid material, directed toward a common point,6, which is the creasing or fold-determining point. One mode of makingthem is to bend a plate of metal into the form illustrated by thedrawings, which plate will provide not only aconvenient means forrigidly securing the turners in proper relation to each other, butprovide sheet-supporting plates extending from one turner to the other,and afford a secure means for attachment to the frame-work, such means,as shown, being a bar, 30, to which the lower edge of the front plate,11, and that of the plate 13 are united, which bar is attached to theside frames, 32 33. When made from a plate of sheet metal a smoothsupporting-surface is provided for the web in its entire travel throughthe folder. Thus the front plate, 11, sustains it throughout its entirewidth as it is carried onto the folder. The back plate, 12, supports onesection of it in its passage from the turner 5 to the turner 7, and theinner plates, 13 and 14, support its two sections as they pass downwardin their doubled condition. Thus, in all positions which it assumes inbeing doubled by this folder, the web is kept smoothly distended withoutbeing unduly strained at any point, as will presently be more fullyunderstood.

For convenience of illustration the web Sis shown inthe figures ascoming from a roll, 31, mounted upon a roller, 34, that is provided.With a tension-strap, 35, that runs over a pulley, 36, Figs. 2, 3. Thisweb passes under a leading-roller,'20, thence through the folder, and istaken up in its folded condition after passing under a leading-roller,21, upon a roller, 22, that is provided with a rotating crank, 23. Fromthe roller 20 the web 8, fully distended widthwise, is laid over theturners 35, so that one section of it shall be stretched over the turner3 and the other over the turner 5, its center or other predeterminedplace of folding lying over the folding-point 6. The sec tion laid overthe turner 3 is carried down ward therefrom while the other section islaid over the turner 5, then laterally to and over the turner 7, fromwhich it is carried downward. In thus disposing the web over theseturners the single ply stretched widthwise from the turners 3 and 5 hasone section, or that part lying at one side of the folding-point 6,carried upward over said turner 3, and thence downward, while the othersection, lying on the opposite side of the folding-point 6, is carriedupward over the turner 5, is then turned at a right angle, carriedtransversely to and over the turner 7, and again turned at a right angleas it is carried downward from such turner 7. The latter section of suchsingle web 8 is thus turned at the point 6 and carried over the othersection, so that the single web is doubled 1ongitudinally and its twoparts or sections lie in parallel planes and constitute a doubled web,.9, the folded point of union 10 being the central or other line whichpassed over the folding-point 6. As the web thus entered into the folderis drawn through the same by means of its doubled portion 9, that is ledunder the roller 21 and attached to the rotating roller 22, it isapparent that it will be doubled on the line 10, so as to lay itssections together and form a product folded once in a longitudinaldirection.

By the action of the folder, constructed as described, the right-handsection of the web will be transferred laterally to the left; but bydisposing the turners 3, 5, and 7 as is shown in Fig. 5 the left-handsection of the web may be transferred laterally to the right. In bothcases the resulting doubled web 9 will have the common plane of its twoparts lying parallel with that in which the single web is stretched. Theweb is thus doubled longitudina-lly upon a line in such relation to theedges of the web as may be determined by the lateral disposition of theweb with respect to the point 6, and the sections of the web will thusbe lapped so that its upper face will form the inner surfaces of thefolded product.

Essential differences exist between this sys-' tem or method of foldingand that commonly practiced, where the line or lines of folding aredetermined by surfaces over which the fabric is turned, as follows:

Heretofore in turning a web or sheets of f as l I I faces over which theweb or sheets are carried are all disposed on one side of the fabric,and are so related to each other that the sections to he lapped togetherare gradually turned and caused to travel in such different planes as toultimately come together or be lapped without the aid of any deviceacting upon the opposite side of the fabric. Such a structure, besidessimplifying the mechanisms, enables one surface of the fabric to becoated with paste, printed, or otherwise ornamented, and whether suchcoating or ornamentation be freshly applied or dry the fabric mayundergo the folding operation without damage or injury thereto.

It has furthermore been the practice to define the line of fold by meansof a folding-edge in contact with the fabric at the line of intendedfold, whereby such fabric is strained, distorted, or broken on the lineof folding by such folding-edge.

In these improvements 'the turners are so disposed with respect to eachother that they do not extend to the point where the fabric is folded,said folders, on the contrary, being blunted, cut away, or set apart, soas to leave the fabric without any bearing-surface at that point. Thefabric, though given the proper direction by the support afforded by theturners, nevertheless remains free or unsupported at the folding-point,and may hence bend or double at that point without being strained by anyrigid supporting-surface or opposing force on either side of it.

Moreover, it will be observedthat in all positions which the web is madeto assume in being folded by the present improvements it is fullydistended widthwise, and therefore has no slack portion, which wouldpermit it to buckle up or to be otherwise distorted from its truecourse. This feature of the in- ,Vention will be found to exist in theimprovements made the subject-matter of separate applications filedrespectively on the 6th, 12th, 22d, and 27th days of May, 1880, and June29,1880. This operation may be carried on at a very high speed, oneequaling that of a printing or other machine manipulating a web by meansof rotating devices; and if the dimensions of the web are thus reducedone-half it follows that an equal reduction of the dimensions ot' themechanisms which are to further manipulate it may be accomplished,whether the same are to fold it into a pack of zigzag folds, as in thePatent No. 8,240, granted to Ambrose and Reynolds, July 22, 1851, or areto impart a second longitudinal fold to it, or divide it into sheets anddeliver them flat or folded, or to impart a second longitudinal fold,then cut into sheets and impart to them a transverse fold, or tomanipulatethe product in any other manner.

. The doubled web may be carried directly to an apparatus for rolling itup or otherwise manipulating it, being for that purpose led over one ormore rollers, as 21. If it is desired to framework at one side of themachine.

with their faces change the direction of its travel, as at aright orother angle to that in which the distended web 8 enters the folder, itmay be done by turning devices constructed on the principle of thosecontained in Patent No. 181,250, dated August 22, 1876. Thislattereffect may, however, preferably be accomplished by the folder in the actof imparting the longitudinal fold to the web. Such an arrangement ofthe apparatus is shown in Figs. 7to 10, in which parts like those foundin the preceding figures are marked with the same characters, so thatthe modification may be readily understood with slight explanation.

The turners 3, 5, and 7 are here so disposed that the distended web 8has its section that is brought over the turner 3 carried downward overthe turner 7, and thence at a right angle outward at one side, and theother section of the web that is brought over the turner 5 is carried ata right angle to its former travel outward, parallel with thefirst-named section. The said web 8 being folded at the point6 anddoubled on the line 10, as before, such doubled web being led over theroller 21 and wound upon a roller, 22, the rollers 21 and 22 in thisarrangement being mounted in a suitable By these means the single webfrom the roller 34 is passed under the roller 20, thence through thefolder, and by it not only doubled but delivered at a right angle to theplane at which it entered such folder. By disposing the turners 3 5 7 asin Fig. 10, the doubled web 9 may be deliveredin precisely the oppositedirection, as is apparent. Now, from an inspection of Figs. 1 and 5 andFigs. 9 and 10 it will be apparent that the angles of relation of theseturners may be varied considerably, and still be within the presentinvention. Thus the outer end of the turner 7 may be swung toward theposition occupied by the turner5 until it stands in a position oppositeto that it has as shown in Fig. 4, the turner 3 being swung or adjustedcorrespondingly downward, and the turner 5 swung or adjustedcorrespondingly upward, as is shownin Fig. 5, and that the turners maybe so moved as to occupy any desired intermediate position. This isequally true of the arrangement shown in Figs. 9 and 10, which show adisposition of the turners that'is the reverse of that illustrated byFigs. 4 and 5. In all its variations the turners forming this folder inany adjustment ofthem stand inv approximately the same plane.

It is to be observed that the point 6 is an imaginary onethat is to say,that, though it is the common point at which the inner ends of theturners would meet it they joined together, such turners have theirinner extremities blunted or cut away so that they, shall not someet. Inthe plate form of the turners the fold of the plate which wouldconstitute this point is cut away. In all cases, therefore, though suchimaginary point 6 is actually the point at which the fold 10 is formed,such fold has no bearingsurface directly beneath it upon which the paperrests. This feature of the invention is applicable to turning-surfacesof any number that are arranged so as to cause a web or sheet drawn overthem to be folded longitudinally, such as are shown in the aforesaidapplications.

In a practical application of this folder it may receive the web 8 fromany source, as the cloth-beam of a loom or cloth-finishing machine, anddeliver its longitudinally-folded product to any of the many forms offolding mechanisms capacitated to impart additional folds to it. The webmay come from a print,- in g-machine of the character herein described,and when folded be delivered by a foldingmachiue which severs it intosheets and folds such sheets transversely, such a one as is shown anddescribed in Patent No. 143,674, dated October 14, 1873, and Patent No.192,034, dated June 12, 1877. If, however, it is attached to aweb-printing machine provided with cutting-cylinders, as 42 43, Figs. 12and 13, which sever it into sheets, such short detached portions orsheets will require to be conducted through the folder by means ofconducting cords or tapes. One system of such taping will now bedescribed as applied to the form of folder shown in Figs. 1 to 6, whichdescription will fully instruct oneskilled in the art as to themodification of taping necessary to be adopted in the modificationsofthe turner herein described.

The lower set of main tapes leading from the cutting-cylinders to thefolder consists, as shown, of four endless tapes, 16 16 16 16 which runover pulleys 24 24 24 24 hung on a shaft, 24, mounted just in advance ofsaid cutting-cylinders. The tapes 16 and 16 pass over one section of thefront plate, 11, of the folder, thus being stretched from the pulleys 2424 under pulleys 25 25 that are mounted on a shaft, 25, so as to standin front of pulleys 27 27 so that their peripheries coincide with theface of the plate 11. From these pulleys said tapes run lightly incontact with the plate 11 over the turner 3, (or pulleys 26 26 hungbetween the plates 11 13, so that their peripheries coincide with thesurface of this turner,) thence down inside of the plate 13 to pulleys27 27 hung on a shaft, 27, and return to the pulleys 24 21 The tape 16runs from the pulley 24 under pulley 25 hung on the shaft 25, with itsperiphery coincident with the surface of plate 11. From thence said taperuns in contact with the plate 11, passing over a pulley, 26 hung in anopening in the plate 11, so that its periphery coincides with thesurface of that plate, and returningunder a pulley, 27 on the shaft 27to the pulley 24 The tape 16 runs from the pulley 24 on the shaft 24,under a pulley, 25, on shaft 25, (the periphery of which pulley standsin an opening in the plate 11 and coincident with its face,) and thencereturns over a pulley, 27 on shaft 27 to the pulley 24 The pulleys 27and 27 are shown in Fig. 6, in which the shaft 25 is broken away toexpose them. These tapes 16 16 run in the same plane to the foot of theplate 11, and as far as they extend upward over said plate they allfollow its surface.

The upper set of tapes coacting with the lower set consists of endlessmargin tapes, 17 17 and an endless center cord or tape, 17, which runsover pulleys 37, 37 and 37 hung on a shaft, 37, mounted justin advanceof the cutting-cylinders and above the pulleys 24 24 24 24. The margintape, 17, runs above the tape 16 from the pulley 37, under the pulley25, over the pulley 26, and returns under a pulley, 38, on a shaft, 50,and over apulley, 39, on a shaft, 39. (This portion of the tape isomitted in Fig. 13, as it runs from pulley 39 to pulley 37 in the sameplane as the cord 17 and would thus obscure said cord.) The margin tape,17*, runs above the tape 16 from the pulley 37, Figs. 12 and 14, underthe pulley 25. From this point it leaves the tape 16, (which isreturned,) and thence lies upon the plates of the folder, which itfollows thus: It bears over the turner 5, extends laterally over theplate 12, bears over the turner 7, and deseending returns over a pulley,38, on the bar 50, thence over a pulley. 39*, on shaft 39, whence it iscarried laterally back to its marginal position by means ofdeflecting-pulleys 40 and 41, from thelatterof which it descends to itspulley 37 The tape or cord 17 runs from the pulley 37 on shaft 37, undera pulley, 25 on shaft 25, thence against the plate 11, over theturning-surface 3, near the foldingpoint 6, descends between the plates13 14, and returns over a pulley, 38 runningon the bar50, (see Fig. 15,)and a pulley,39 ,on shaft 39, thence over a deflecting-1.)uIIey, 39 toits pulley 37 The surface speed ot'these tapes will be slightly greaterthan that of the cutting-cylinders, so that the forward end of thepartially or completely severed web (when nipped between the tapes 16 1616 16 and tapes 17 17 on the line of contact with pulleys 25 25 25 25will be advanced fast enough to detach such forward end to form a sheet,which sheet (or one formed by completely severing the web) will beadvanced to provide a working distance between successive sheets, as iscommon in web-printing machines. Each sheet will be supported andcarried onto and over the folder by these tapes and will have itssections folded laterally one upon another, so as to double the same ona line parallel with its line of travel, as will be readily understoodfrom the former description, said tapes controlling the sheet until inits once-folded condition it leaves said folder. From the point wherethe tapes or cords 17 17 17 return such folded sheet is guided onward bymeans of auxiliary endless tapes 15 15 and 18 18 stretched as follows:The tapes 18 18 run over pulleys 48 48 hung on shafts and so located asto lie in the planes in which the folded plies of the paper lie asthey-leave the plates 14 13, thenceover pulleys 44 44 and return overpulleys 44 44 by which said tapes are stretched horizontally to coactwith tapes 19 19 that are stretched from pulleys and its companion topulleys 51' 51 area means of delivering the paper when it is foldedtransversely. The tapes 15 15 run over pulleys hung on the shaft 27 andreturnover pulleys 49 49 The tapes 16 16 might be extended to take theplace of the tapes 15 15 and would then return from the pulleys 49 49 tothe pulleys 24 24 It is obviousthat the tapes 15 15 and 18 18 might leaddirectly to a second taped folder composed of turners, or to a fly whichwould deliver the longitudinally-folded sheets in a flat pile, or to anyof the well-known forms of rotating folding mechanism. This tapedfolderis shown in Figs. 12, 13 as combined with a folder like that ofthe Patent No. 171,196, December 14, 1875. Said folder consists of adouble rotating folding-blade, 60, that is supported in a rotatingcarrier, 61, said folder operating to project one'of the folding-bladesinto the nip of the pulleys 44 44 and 45 45 at each rotation of itscarrier, whereby a sheet caused to descend before said pulleys will bedoubled by said folding-blade into the nip of the pulleys, as shown bydotted lines, and will thus be folded transversely on any predeterminedline, and, thus folded, will be delivered by the tapes 18 18- and 1919". The smooth descent of the paper between these pulleys and thefolder is aided by guides 62 and 63. Conductors 65 may extend betweenthe tapes 15' 15 and 18 18 to aid the descent.

of the folded sheet.

The transversely-folded sheet may be arrested in its passage between thetapes 18- 18 and 19 19 or the unfolded sheet may be arrested whilepassing between the tapes 18 18 and 15 15 and be struck by afolding-blade between a pair of folding-rollers which are properlyplaced with respect to the plane in which the sheet is carried by saidtapes.

The space intervening between the surface of the cutting-cylinders andthe pulleys 24 24 24 24 and 37, 37 and 37 may be spanned by conductorsor conducting-cords 66 66, that run in grooves in said cylinders andover pulleys 67 67 mounted on the shafts 37 and 24.

If the cutting-cylinders 42 43 do not entirely sever the webtransversely, but, partially severingit, leave it connected at two ormore places, the system of taping may travel at the same speed as thecutting-cylinders, or fast enough to keep it taut, but not sever, thusenabling the connected sheets to rnnat a lesser speed than whencontrolled by accelerated tapes. In this case the sheets may beseparated, after leaving the turners, by means of fast-runningnipping-rollers.

A combined cutting and folding mechanism such as is described in PatentNo. 143,674, dated October 14, 1S73- -one that embodies a otherproportion of such width, and whether severed transversely or not, maybe carried into the folder on top or beneath the main web, and thus beincorporatedwith it, said severed or unseveredsupplement web beingdelivered with the main web to form supplement sheets of differentsizes, as required.

It will be understood that the cutting-cylinders 42 43 may be removedand the folder receive sheets from any one of the various kinds ofmachines adapted to produce or manipulate fabrics.

It is obvious that the web or sheets folded once longitudinally by thisimproved folder may be converted into a tube suitable for various usesby laying a line of paste upon one of its edges as the fabric passesthrough the folder. This pasting device may be of any well-known form,and be located at any proper point, as a disk, 100, placed near the baseof the plate 11. (See Fig, 1.)

In Fig. 16 I have illustrated the combination, with printing and cuttingmechanisms, of two longitudinal-folders of the character hereindescribed. The combination and operation of these folders have been sothoroughly hereinbefore described that no further explanation isrequired here. Though they are arranged in horizontal planes, theirfunction and action remain the same. I have here shown a web of paper,8, as being led from its supply-roll 81 between cylinders 70 71, whichillustrate the type and impression cylinders of a printing-machine. Thisweb, in passing over the turners 3 5 7 constituting the primary folder,will be doubled or folded longitudinally upon a central line, and in itsdoubled condition will pass over the turners 3, 5, and 7 constitutingthe secondary longitudinal folder, and thereby vbe a second time foldedlongitudinally upon a line parallel with its first longitudinal fold.Thus folded, the web is led through a cutting and a folding mechanismitmight be through acombined cutting and folding mechanismas shown and ashas been hereinbefore described, and which, in this figure, isillustrated as consisting of two rotating carriers, 81, the one suppliedwith afoldin g or creasing blade,44,an d the other with fold-seizingjaws 85 86, the latter a moving jaw, which carriers are provided, atproper points opposite to those occupied by the folding-blade andnipping-jaws, with a cutting mechanism of any ordinary construction. Inpassing through these cylinders the longitudinally-folded web will befolded transversely by means of the blade 44, its doubled bight IIO orfold being entered into the slot provided between the jaws S6, andsecured there by the latter jaw closing upon it. As the cylindersrevolve the folding-blade 44 will be withdrawn and the paper carriedonward by the jaws 85 86 until, the proper length having passed betweenthe carriers 80 81, the web will be severed by the cutting mechanism,and the detached portion of the sheet thus formed will have its forwardand rearward portions laid together to complete the fold, and the foldedsheet will be piled beneath the carrier 81 by reason of the releasementof its forward-folded edge by the opening of the jaws 86, said operationbeing performed substantially in the same manner as is described in saidPatent No. 143,674.

folding-machines and cutting mechanisms may be employed.

While I have shown two longitudinal-folders combined with each other, itis obvious that any other number may be thus arranged.

The following is alone claimed herein 1. A longitudinal foldingapparatus consisting of turners that bear upon one surface of the fabriconly, and which are arranged at such relative angles as to guidetogether the two sections of a fabric drawn over them, all substantiallyas described.

2. A longitudinal-folding device consisting of three turners that arearranged to bear upon one surface of the passing fabric and guide itstwo sections together, substantially as described.

3. The combination, with the turners 3, 5, and 7, of plates 11, 12, 13,or 14:, connecting them together and forming supporting-surfaces for theweb or sheet, substantially as described.

4. The combination, with turners arranged to bear upon one surface ofthe passing fabric and guide its two sections together, of aleading-roller, as 20, substantially as described.

5. The combination, with turners arranged to bear upon one surface ofthe passing fabric and guide its two sections together, of a leading-roller, as 21, substantially as described.

6. The combination, with turners arranged to bear upon one surface ofthe passing fabric and guide its two sections together, of leadinrollers, as 20 an d 21, substantially as described.

7. The combination, with one or more longitudinal-folders, consisting ofturners that are arranged to bear upon one surface of a web passed overthem and fold the same longitudinally by guiding its two sectionstogether, of a cutting mechanism severing said web into sheets, allsubstantially as described.

But, as has been hereinbefore re-- marked, any other of the well-knownrotary S. The combination, with one or more longitudinal-folders, eachconsisting of turners that are arranged to bear upon one surface of aweb passed over them and fold the same longitudinally by guiding its twoside sections together, of a folding mechanism operating to imparttransverse folds to the same, all substantially as described.

9. The combination, with one or more longitudinal-folders, eachconsisting of turners that are arranged to bear upon one surface of aweb passed over them and fold the same longitudinally by guiding its twoside sections to gether, of a cutting mechanism severing the web intosheets and a folding mechanism operating to impart transverse folds tothe same, all substantially as described.

10. The combination, with one or more longitudinal-folders, eachconsisting of turners that are arranged to bear upon one surface of aweb passed over them and fold the same longitudinally by guiding its twoside sections together, of a printing mechanism, all substantially asdescribed.

11. The combination, with one or more folders constituted by turnersthat are arranged to bear upon one surface of a fabric passed over themand fold the same longitudinally by guiding its two side sect-ionstogether, of tapes arranged to carry the fabric through the folder, allsubstantially as described.

12. A folder consisting of turners disposed at such angles to each otherthat aweb or sheet passed over them will have its sections lappedtogether, and thus be folded longitudinally, which said turners havetheir inner ends blunted or removed, so that the fabric shall not be injuriously strained thereby atits fold in g-poin t, substantially asdescribed.
